Question

英语中两个句子之间什么时候用逗号隔开,什么时候用分号呢

Answer 1

说实话，英语中两个句子一般都用句号的。逗号，通常是一些特殊的词，比如however在句中的话，前后都要加逗号，如果在句首，后面要加逗号。再就是一些关系特别紧密的，中间可用and、but等连接词的，可以用逗号。分号，就像一楼所说，两个平行或并列的部分，说明一个问题的两个方面。
学英语学了十几年了，句号是用的最多的，分号一般没有用过，呵呵。希望可以帮助到你。

除了两位亲讲的, 再补充其他知识:

当你看见有but, and, also, as well as, because, so 等等的字眼时. 例句:

I didn't wake up on time this morning so I was late for school. (逗号在 so 前面是可有可无, 一般不会写因为第二个句子自己不能独立, 不能算完整所以可有可无, 只是为原本的句子做注解而已)

当两个句子都是独立时, 逗号就一定得在but, and, also, as well as, because, so
等等词后面用上, 如:
I didn't wake up on time this morning.
I had a very bad headache. 两句都是独立句. 加在一起时, 逗号必须出现:
I didn't wake up on time this morning, because I had a very bad headache.

如果是用however, therefore, thus, on the other hand诸如此类的, 其实是要用 ; <<分号
例句: I didn't wake up on time this morning; therefore, I was late for school.
2. I didn't wake up on time this morning; however, I didn't have to anyway as it is a public holiday.

逗号与分号加在一起的的例句:
I didn't wake up on time this morning, I even ran into traffic, and my bike was broken; therefore, I was very late when I finally got here.

我不太会解释但希望例句多少有点帮助~~~

逗号 一句话没说完 接着说
分号 前后两个句子是两个部分 都是完整的含义 可以换成句号
